Modular Subsoil Drainage System for Rapid Installation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional subsoil fluid absorption systems lack design flexibility, installation adaptability, and are labor-intensive, often requiring additional materials and specialized equipment, which can damage surrounding areas during installation.
Innovation Solution
The PME unit, comprising spaced support modules and a perforated support pipe, provides structural integrity, increased interfacial area, and void space, allowing for flexible installation configurations, reduced labor, and improved fluid flow, with options for pressure or gravity systems and easy connection using standard pipe fittings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If conventional rock aggregate systems are used, then fluid absorption function is provided, but installation is labor-intensive and time-consuming requiring specialized equipment
Solution Approach 1:
The patent combines the rock aggregate reservoir function and the distribution pipe function into a single integrated module. The distribution pipe is embedded within the rock aggregate structure, eliminating the need for separate aggregate placement and pipe installation operations. This merging of functions directly addresses the contradiction by reducing installation complexity while maintaining fluid absorption capabilities.
Solution Approach 2:
The system is divided into modular units that can be pre-assembled and then quickly installed. Each module contains integrated components that can be independently handled and positioned, reducing the need for specialized equipment and labor-intensive on-site assembly. This segmentation enables faster installation while maintaining system functionality.
2Adaptability or versatility
If conventional chamber systems are used, then fluid holding capacity is provided, but design flexibility and installation adaptability are limited
Solution Approach 1:
The system uses adjustable and configurable components that can be adapted to different installation conditions and design requirements. The modular nature allows for dynamic configuration adjustments in terms of orientation, connection patterns, and integration with existing infrastructure, providing design flexibility without sacrificing void space for fluid holding.
3Ease of manufacture
If rock aggregate is moved and distributed in excavation, then fluid absorption system is created, but surrounding lawn areas are damaged and installation time increases
Solution Approach 1:
The system components are pre-assembled and pre-configured before installation. The distribution pipe is already positioned within the rock aggregate structure during manufacturing, eliminating the need for on-site aggregate movement and distribution. This preliminary action prevents lawn damage by avoiding heavy equipment operation in surrounding areas and reduces installation time by eliminating on-site assembly operations.
4Reliability
If additional fill is added for vertical separation, then adequate separation to groundwater is maintained, but installation complexity and material requirements increase
Solution Approach 1:
The integrated module serves multiple functions simultaneously: it provides fluid distribution, maintains vertical separation through its structural design, and eliminates the need for additional fill materials. The module's own structure is designed to maintain adequate separation from groundwater, making additional fill unnecessary and reducing installation complexity.
